CMTA has released CMTAT Confidential: tokenize an asset or issue a stablecoin with the amounts kept private. Built on CMTAT Solidity for compliance and OpenZeppelin's ERC-7984 for confidential tokens. v1.0.0 audited by OpenZeppelin, sponsored by Zama. github.com/CMTA/CMTAT-C... #tokenization #FHE
How do you add on-chain compliance without modifying the token contract? Chainlink ACE is now integrated into the open-source CMTAT framework, enabling policy-based compliance and access control. Implementation on GitHub: github.com/CMTA/CMTAT-ACE #tokenization #ethereum
Nethermind implemented a way to represent FIX (Financial Information eXchange) data on-chain using deterministic encoding and a Merkle root commitment instead of storing raw messages. This enables efficient verification of structured trade data without on-chain parsing. github.com/CMTA/CMTAT-FIX

Using only natural language instructions, researchers were able to bypass Google Gemini's defenses against malicious prompt injection and create misleading events to leak private Calendar data.
ERC-1643, part of ERC-1400, is one of the oldest tokenization related standard on Ethereum (2018) developed by PolymathNetwork. It allows to manage on-chain document which is very useful for tokenization and RWA. More information on the Ethereum magician forum: ethereum-magicians.org/t/erc-1643-d...
The latest release of CMTAT Solidity (v3.1.0), a security token framework for on-chain RWA, includes now Chainlink CCIP support for seamless cross-chain transfers. Available on GitHub
How do you tokenize RWAs on Solana? CMTA just released a new specification leveraging the Token Extensions Program (Token-2022). Now available on GitHub: github.com/CMTA/CMTAT-S... Glad to have contributed through my work at Taurus

Yep, I've been pwned. 2FA reset email, looked very legitimate. Only NPM affected. I've sent an email off to @npmjs.bsky.social to see if I can get access again. Sorry everyone, I should have paid more attention. Not like me; have had a stressful week. Will work to get this cleaned up.

A cascading supply chain attack that began with the compromise of the "reviewdog/action-setup@v1" GitHub Action is believed to have led to the recent breach of "tj-actions/changed-files" that leaked CI/CD secrets.
